A convergent asymmetric total synthesis of (+)-danicalipin A is accomplished, in which two chlorinated fragments are stereoselectively joined by 1,3-dipolar coupling, leading to the confirmation of the absolute configuration of the natural product.
(+)-丹卡林 A 的收敛不对称全合成得以实现,其中两个氯化片段通过 1,3-偶极环加成立体选择性地连接,从而确定了天然产物的绝对构型。
